KDDI has a prototype Android app that can monitor your brainwaves. You have to wear a silly headband sensor and play an even dumber video game but the app graphs your brain's neural activity and concentration levels after you're done.

See-through things are cool. Anyone who ever pined for a transparent Game Boy (or was lucky enough to own one) knows that. Even if flippers are unfashionable, I still want to hotfoot it over to Japan to scoop this up.

This kids-friendly KDDI's cellphone keeps children safe from kidnapping, with a built-in GPS, and a ring that gets laser-soldered to their noses. I mean, I guess—otherwise, how can you prevent kidnappers from tossing the cellphone away? [Dvice]

At Japan's CEATEC show, Toshiba and KDDI are demonstrating a modified Toshiba T002 phone that's powered by a direct-methanol fuel cell (DMFC) and Li-Ion battery. More advanced than previous prototypes, it runs for 320 hours on a squirt of methanol.

Leave it to a Japanese cell phone carrier to figure out a way to breed robots and cell phones. KDDI's iida Polaris is a rolling robot with a touchscreen candybar phone inside that can keep your life in order.

Japanese phone king KDDI is showing off a MicroSD card with built-in Wi-Fi, sorta like those photo-uploading Eye-Fi cards everyone loves so much. Actually, they're exactly like that, except, well, much smaller.

Apparently, Japanese carriers KDDI and DoCoMo are being totally overwhelmed by porn downloaders on their 3G networks. I don't know what they expected to happen when porn services started offering movies for wireless download.

Motorola is building a generally unremarkable "au Box" portable set-top box for Japanese electronics company KDDI. But one part of their plan stands out: It'll run Android. UPDATE: According to Motorola, this KDDI box will not run Android. See their full response below.

Proving again that Japan has the prettiest phones in the world, au by KDDI has released its Fall and Winter lines, showing off eight new models with emphases on super bright and big Organic EL screens, multimedia “au BOX” connectivity, and a funky mobile personal trainer and calorie counter called “Karada Manager.”…

As though the flood of WTF-type phone concepts weren't enough, KDDI revealed a proof of concept for a wireless, color, e-paper display they have in the works. The idea is that a cellphone would be used to broadcast a signal to the display via infrared. The 13.1-inch display can display up to 4,096 colors and refresh…

The term "word's first" gets thrown around a lot with gadget releases, but with kooky creative phone maker KDDI behind the project, I'm a lot less skeptical about the claim that they have developed the first 3D cellphone screen. You can't get the full effect from the images here, but it appears that this prototype…

The KDDI AU Design Project bunch over in Japan have stumped up with this latest concept phone for music cellphones of the future. And it blends two things we like a Giz: funky cellphone tech and Transformers. In fact Box To Play is less "robot in disguise," and more "hi-fi in disguise" because when it's a phone, it's…

This phone, inspired by the multiple layers of wooden sandwich in plywood, is of multiple slider design. Inside, and separated by tabs, are a printer, projector, gamepad and sliding downward, a dialpad. It's as cool as it is impossible to build, and so KDDI labs should feel proud for making an imaginary device with so…

Evolution Robotics ViPR visual search technology is coming to the iPhone this June. ViPR allows you to take a photo of any movie, CD or book, send it to a server, and automagically get an email back loaded with information and links pointing to YouTube videos or iTunes Music Store links. It will also be deployed in…

You can't buy cellphones from KDDI unless you live in Japan. You can't even import em and use em here. But clicking around their website and exploring their spring line up of handsets feels like a museum. From the future. I've explored random Japanese handsets before and still enjoy looking at them, no matter if the…

While IR is still quite useful for certain things, transferring data between devices is something very few people still use it for. Japan's KDDI R&D labs, however, have managed to increase the transfer rate 250 times to 1Gbps with a semiconductor laser that blinks incredibly fast. Although 1Gbps is fast, it doesn't…
